Security Analytics Engine 1.2 - User Guide

Adding a new shared risk policy

To add a new shared risk policy

1. On the Shared Policies page, click the button to open the Add Shared Policy dialog.
2. In the Policy Name field, enter a unique display name for the shared risk policy. This name is only used within the Administration web pages.
3. (Optional) In the Description field, enter a brief description of the shared risk policy. This description is only used within the Administration web pages.
4. (Optional) Select the Disable Policy Override check box to disable overrides for this shared risk policy. This setting applies to all applications that use the shared risk policy.
5. (Optional) Use the Alerting section of this dialog to set up email alerts for this risk policy. Click Alerting to display the following settings:
   • Notify Admin - Select the check box to begin sending email alerts and in the field enter the email address of the person that will be receiving the alerts.
   • Notify User - Select the check box to send an email alert to the user attempting access when they exceed a certain score.
   • - If Notify User is selected, click this button to open the Customize User Alert Email dialog which is used for customizing the subject and descriptive body text of the alert email sent to the user. Once edits are made, click Accept to close the dialog.
   • Alert When - Select one of the following options:
     • Always - Send alerts when a risk policy is evaluated by the application and when the application updates user behavior data.
     • Only when specified - Sends an alert when the risk policy used for evaluation generates a risk score for the application.

   • Scores <nn> Or More - In this field enter the minimum risk score (1 to 100) a user must receive in order for an alert to be sent.

   IMPORTANT: When multiple, identical alerts for the same risk policy occur within a 5-minute period, the Security Analytics Engine only sends one alert. If alerting is used in risk policies with multiple conditions, you may want to assign different scores for each condition since there is a chance that a user may attempt access twice in that 5-minute window and trigger different conditions yet still cause the same score.

6. Click the button in the upper right corner to open the Select conditions to monitor dialog.
7. Select the check box to the left of a condition name to add that condition to the risk policy. All selected conditions remain highlighted so you can track which conditions are being used in the risk policy.

8. Repeat Step 7 until you have selected all the conditions to apply to the risk policy.

   Multiple conditions of the same type are allowed in a risk policy and are useful for adding levels of risk to a type of condition. For example, one Abnormal Browser condition can increase a risk score if the browser was unused for 15 days while a second Abnormal Browser condition can further increase the risk score if the browser was unused for 30 days. If a browser that has not been used in over 30 days is used for access, both will be triggered causing both assigned scores to be included in the risk score.

9. Click the OK button to close the dialog.

10. The Add Shared Policy dialog displays the selected conditions according to category. Each condition has a slider associated with it that is used to assign a percentage to the condition. Assign each condition a percentage according to how much of a risk you consider a user that triggers the condition during an access attempt.

    NOTE: Hovering over a condition displays a button. Clicking this button displays the condition’s description.

11. (Optional) Each condition can also be assigned modifiers. These modifiers are used to either increase or decrease the score of a triggered condition in cases when a modifier is also triggered. This allows you to control how a single condition is calculated without lessening or intensifying the effect of another condition which should not be impacted by those same, or possibly any, modifiers. The following steps are required for adding a modifier to a condition:
    • Locate the condition which is to be assigned a modifier.
    • Select the button located to the left of the condition name to open the Select condition modifiers dialog.
    • On the Select condition modifiers dialog, select a check box located to the left of a condition name to add that condition as a modifier of the original condition. All selected conditions remain highlighted so you can track which conditions are being used as modifiers of the original condition.
    • Click OK to close the dialog.
    • Each modifier will now appear listed beneath the original condition with a scroll bar set at 100%. Move the slider in increments of 10 to set the impact each modifier will have on the condition score. Depending on how each modifier was configured on the Conditions page (Can increase risk, Can decrease risk, or Can both increase or decrease risk), the following settings are available:
      • 0% - A modifier set to this percentage automatically causes the condition score to be 0% regardless of any other modifiers triggered. (Can decrease risk or Can both increase or decrease risk)
      • 10%-90% - A modifier set between these two percentages decreases the condition score when triggered. (Can decrease risk or Can both increase or decrease risk)
      • 100% - A modifier set to this percentage will not affect the condition when triggered. (Can decrease risk, Can increase risk, or Can both increase or decrease risk)
      • 110%-200% - A modifier set between these two percentages increases the condition score when triggered. (Can increase risk or Can both increase or decrease risk)
12. (Optional) To preview possible risk scores that can occur for the risk policy, click the button in the upper right corner of the dialog to enable Preview Mode. Edits to the risk policy are allowed while preview mode is active.
    • Select the check boxes to the left of any conditions or modifiers to preview the risk score that occurs if they are triggered during an access attempt. The Risk Score field at the top of the dialog updates as selections are made.
    • Click the button to close preview mode.
13. Once each condition and modifier has been assigned a percentage, click Save to save the shared risk policy and return to the Shared Policies page.
